Device Overview

Summary

The MRF24WN0MA is a low-power, 2.4 GHz, IEEE 802.11n-compliant, surface mount module with all associated RF components:  crystal oscillator, bypass and bias passives with integrated MAC, baseband, RF and power amplifier, and built-in hardware support for encryption..

The integrated module design frees the designer from RF and antenna design tasks and regulatory compliance testing, ultimately providing quicker time to market.

The MRF24WN0MA module is designed to be used with Microchip's MPLAB® Harmony Integrated Software Framework. The integrated framework implements the Application Programming Interface (API) that is used for command and control, for management, and data packet traffic. The MPLAB Harmony basic framework is free to download at http://www.microchip.com/harmony.

The MRF24WN0MA module is approved for use with the integrated PCB trace antenna.  The MRF24WN0MA module has received regulatory approvals for modular devices in the United States (FCC) and Canada (IC). Modular approval removes the need for expensive RF and antenna design, and allows the end user to place the MRF24WN0MA module inside a finished product and does not require regulatory testing for an intentional radiator (RF transmitter).  The MRF24WN0MA module is an R&TTE Directive assessed radio module for operation in Europe. The module tests can be applied toward final product certification and Declaration of Conformity (DoC).
